It makes him a German supremacist and an "amazinhunk" as this BBS translates the popular derogatory term... but not a liar.
There are people even today that believe in national socialism, communism, and all sorts of political and religious extremism, regardless of what has happened in the past.
That doesn't make them liars.
Anyways, this is getting very off topic and into rule-violation territory. So that's it.
